|
||
|
|
<p>Dependent LU Requester Support (DLUR) allows dependent secondary logical
|
||
|
|
units (LU 0, 1, 2, and 3) an entry point into the APPN network. DLUR support
|
||
|
|
gives the appearance of having an adjacent connection to VTAM®, but allows
|
||
|
|
traversing the APPN network through intermediate nodes.</p>
|
||
|
|
<p>DLUR supports the following controllers, displays, and printers:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Host devices, including 3270 emulation (*EML), remote job entry (*RJE),
|
||
|
|
and program-to-program communications (*PGM)</li>
|
||
|
|
<li>SNA Passthrough upstream devices</li>
|
||
|
|
<li>DHCF display devices</li>
|
||
|
|
<li>NRF display and printer devices</li>
|
||
|
|
<li>SNUF devices (DSNX)</li></ul>
|
||
|
|
<p>The normal SSCP-PU and SSCP-LU flows for dependent LUs are encapsulated
|
||
|
|
in a control point server (CP-SVR) pipe. This pipe consists of two LU 6.2
|
||
|
|
sessions: </p>
|
||
|
|
<ul>
|
||
|
|
<li>Send</li>
|
||
|
|
<li>Receive</li></ul>
|
||
|
|
<p>At the primary end of the pipe is a <span class="bold">Dependent LU Server
|
||
|
|
(DLUS)</span>. At the secondary end of the pipe is a <span class="bold">Dependent
|
||
|
|
LU Requester (DLUR)</span>. DLUS and DLUR support the activation and deactivation
|
||
|
|
of dependent physical units (PUs) and logical units (LUs) in the APPN network.
|
||
|
|
The pipe consists of a pair of LU 6.2 conversations where two APPC applications
|
||
|
|
(DLUR and DLUS) exchange dependent SNA SSCP flows. The flows are encapsulated
|
||
|
|
in a general data stream (GDS) variable and sent in LU 6.2 logical records.
|
||
|
|
The pair of conversations that are used to transmit encapsulated SNA is called
|
||
|
|
the CP-SVR Pipe.</p>
|
||
|
|
<p>To configure DLUR, see the article <a href="rzajtcfgstps.htm#cfgstps">Configure Dependent
|
||
|
|
LU Requester</a>.</p>
